Combine the convenience of wireless data delivery with the intelligence of noncontact flow monitoring. Using wireless Hach FL900 Series flow loggers and noncontact FLO-DAR AV sensors, this system captures flow data with a high level of accuracy, dramatically reduces required maintenance and significantly limits the risk of lost data due to sensor downtime. And with wireless, real-time data is... more

Hach Data Delivery Services (DDS) is a flow-monitoring service in which, for a fixed monthly fee, Hach provides all the equipment, resources and support you need to acquire your flow data. DDS utilizes wireless Hach FL900 Series flow loggers and noncontact FLO-DAR AV Sensors to transmit flow data directly to your desktop. Click here to view a video about Hach DDS. more

Hach’s level-alarming solution—which pairs a Hach US9001B ultrasonic sensor with Ballast and a wireless Hach FL900 Series flow logger—provides wastewater professionals with an economical approach to monitoring and capturing data from multiple sites in their network. No confined space entry is ever required for either installation or maintenance, and alarm alerts can be automatically delivered to... more

The Hach FL900 Series flow logger is a rugged, reliable and innovative data logger that is equipped to handle difficult environments. The FL900 has up to four plug-and-play sensor ports that auto-detect sensor types, facilitating rapid setup. An LED display informs users on site if the logger is functioning properly. A wireless-enabled option, providing real-time data transmission and alarming,... more

Using digital Doppler radar velocity-sensing technology and ultrasonic level sensing, the FLO-DAR AV sensor advances open-channel flow monitoring by measuring from above the wastewater flow. This dramatically reduces the possibility of sensor fouling and the resulting loss of data. It also means that it can be used under a wide range of challenging flow and site conditions. more

The Hach FH950 handheld flowmeter with electromagnetic sensor is designed for use in both environmental and sewer/wastewater flow measurement scenarios. It can be utilized for profiling water current in streams and rivers, providing redundant verification of wastewater flow data and selecting an optimal site for metering. The intelligent sensor measures both velocity and level, and the FH950... more
